TVILLIAM LAPXVORTI'I, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO THE HOPEDALE ELASTIC FABRIC COMPANY, OF SAME PLACE.

WOVEN ELASTIC OR CORDED FABRIC.

SPECIFICATION forming part of Letters Patent No. 454,366, dated June 16, 1891. Application filed May 25, 1889. Serial No. 312,080. (No specimens.)

To all whom it may concern:

Be it known that 1, WILLIAM LAPWORTH, of Hopedale, county of lVorcester, State of Massachusetts, have invent-ed an Improvement in \Voven Elastic or Corded Fabrics, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

IO This invention has for its object the pro duction of an elastic or corded fabric having back and face of different colors without binder-warps.

Heretofore elastic fabrics without binders r 5 have been woven and of distinct and different colors at the back and face, as in United States Patent No. 283,100. The fabric described in that patent contains face and back warps and the pattern is completed in eight p cks, each face warp standing up for six picks and down for two picks, the back warps being down for six picks and up for two picks.

In my improved fabric the pattern is completed in six picks. The face warp-threads 2 5 in turn are each up for four picks and down for two picks, the back warps being down for five picks and up for one pick, such order of moving the warp-threads atthe back and face of the fabric affording such crossings as to bind the rubber into the fabric more firmly than can be done in an eight-time motion. When no11-elastic cords or heavy warps are substituted for the rubber warps, a corded fabric will be produced.

Figure 1 shows on an enlarged scale the warp and weft of a fabric made in accordance with this invention. Figs. 2 to 7, inclusive, snow the positions of the warp and weft for each pick of the pattern; and Fig. 8 shows the first pick of the repeat of the pattern. Fig. 9 is a longitudinal sectional diagram illustrative of my improved fabric.

Referring to Fig. 1, the warp-threads a Z2 0 are face threads, and those marked (Z e fare back threads and of a different color from the face threads.

The threads marked 1 are supposed to be of india-rubber.

The weft-threads are designated by the let- 5o ter 10.

All the warp-threads a are held in the heddles of one harness-frame and those I) in another, and so on throughout for all the other threads 0, (Z, c, f, and 0', so that all the threads designated by like letters are moved in uni- 5 5 son.

I have herein shown enough warp-threads to fill two spaces of the reed and enable both back and face of the fabric to presentathreeleaf twill, three threads for both the back and 6c: face being required in each dent to make a full twill at each side of the fabric.

Fig. 2 shows the position of the warp for the first pick, and Figs. 3 to 7 the succeeding picks to complete the pattern, Fig. 8 being like Fig. 2, or showing the first pick of the repeat.

Referring to Fig. 2, showing the first pick, the face thread co is down and it remains down for the second pick, as shown at Fig. 3, but is raised in Figs. 4 to 7, which show the third to the sixth pick, it being down again in Fig. 8. The back thread d is up in Fig. 2, down in Figs. 3 to 7, being raised in Fig. 8. The face thread Z) is up in Figs. 2 and 3 and down in Figs. et and 5, and up again in Figs.

6 and '7 and in Fig. 8, which is the commencement of the repeat. The rubber 9', as it will be noticed, is up at one pick and down at the next pick alternately, or, in other words, on opposite sides of the weft at alternate picks. The back thread 6 (see Fig. 2) is down, as also in Fig. 3; but it is up in Fig. land down in the remaining figures. The face thread 0 (see Fig. 2) is up and it remains up in Figs. 3, 4t, and 5, being down in Figs. 6, 7 and up in Fig. 8, and the back thread f (see Fig. 2

is down and it remains down in Figs. 3, 4, and 5, coming up in Fig. 6, which represents the fifth pick, and being down in Figs. Zand 8. 0

The fabric described may be woven in any loom usually employed to weave elastic fabrics, a single shuttle being used.

The herein-described fabric, composed of independent sets of face and back warps of different colors, rubber or cord warps and a weft, the face warps being above or on the face side of the weft for four picks and below or on the back of the weft for two picks, and

the independent back warps being below or In testimony whereof I have signed my on the back of the weft for five picks and name to this specification in the presence of above or on the face side of the weft for one two subscribing witnesses.
